Head louse. Coloured scanning electron micrograph (SEM) of a claw of a human head louse (Pediculus humanus capitis) clinging to a human hair. The head louse inhabits the hair of the head, glueing its eggs (called nits) to the shafts of individual hairs. It lives on blood, which it sucks from the scalp. The wounds left by the lice cause intense itching, which can lead to dermatitis and impetigo (a bacterial infection of the skin). The problems are compounded by reflex scratching of the bites. The lice can spread from head to head by close contact. Nits and lice can be killed by washing the hair with special medicated shampoos. Magnification x88 at 6x7cm size.
